This week the Czech newsmagazine Tyden reported on a theory that the
so-called Czech basin, or massif, which makes up most of Bohemia, may have
been created by a meteorite hitting the area around 2 billion years ago.
The impact of the celestial object hitting the Earth would have been
comparable to the force of many combined nuclear blasts. Generally, the
Czech basin is thought to have been formed through plate tectonics, but
now
some scientists are considering a different possibility..
